The Strategic Plan will cover both the long-term global strategy for each Product and, on a rolling [***]-month basis, the more detailed activities Novartis will perform over the course of the next [***] months, including overview and timing of the CVOT Novartis will conduct for the CVRR Indication Novartis will pursue for each Product.

As determined by [***], the activities and strategy in the Strategic Plan will be driven by emerging data, the shifting competitive landscape over time, and scientific, reimbursement environment, and medical factors that impact regulatory, development and commercialization strategies.

When materially updating the Strategic Plan, Novartis will include the following components:

(i)                                    The objectives of the Strategic Plan and estimated timelines;

(ii)                                The estimated timing and launch sequence per Indication for each Product;

(iii)                            The key global Clinical Studies (including the CVOT Novartis will conduct), including estimated timelines for the key milestones associated with such studies, the primary and secondary endpoints,

*  ***Confidential Treatment Requested

approximate size and duration of such studies, and patient populations, in reasonable detail as determined by Novartis, that Novartis will conduct for each Product; and

(iv)                             Key elements of the planning and strategy to support Development, Manufacturing, Regulatory Approvals and Commercialization (including [***] and [***]).

Each time Novartis exercises its Option to a Product, such Product will be included in the Strategic Plan in accordance with the principles set forth in this Section 6.1.

6.2.                            Initial Strategic Plan. Novartis will deliver an initial draft Strategic Plan for each Product to Akcea within [***] ([***]) calendar days after the date Novartis licenses a Product under Section 5.1.

Until Regulatory Approval of a Product, Novartis will provide Akcea with material correspondence with and material submissions (NDA, MAA, briefing documents, priority review or breakthrough request) to any Regulatory Authority in each Major Market for such Product, sufficiently in advance of providing such correspondence or submission to the applicable Regulatory Authority to enable Akcea to provide comments on the contents thereof.  In the event Akcea does not provide comments within [***] calendar days from receipt (or shorter notice as reasonably indicated by Novartis), it is agreed that Novartis shall be entitled to submit such submission or correspondence as the case may be. In addition, until Regulatory Approval of a Product, Novartis will notify, at JDCC meeting, Akcea of any planned significant meetings with a Regulatory Authority for a Product in a Major Market, and will, at Akcea’s request, consider in good faith inviting Akcea (or its Affiliate) to participate with one representative [***] under the direction of Novartis in any such meeting. For the avoidance of doubt, Akcea’s performance under this Section 6.6.1 shall be at no cost to Novartis.

6.6.2.                  Akcea Cooperation.

(a)                                 At no cost to Novartis, on a Product-by-Product basis, within [***] ([***]) calendar days after Akcea grants Novartis the license for such Product under Section 5.1, Akcea will transfer the IND for such Product to Novartis together with all regulatory documentation (including pending drafts) related to such Product.

(b)                                 Following such IND transfer under Section 6.6.2(a), if requested by Novartis and mutually agreed by Akcea (such agreement not to be unreasonably withheld, delayed or conditioned), Akcea shall cooperate with and provide reasonable assistance to Novartis in connection with filings or submission to any Regulatory Authority relating to the Products, including by executing any required documents, providing access to personnel and providing Novartis with copies of all reasonably required documentation. After the first [***] hours of Akcea’s time for any assistance under this Section 6.6.2(b), Novartis will compensate Akcea in accordance with Section 7.10 for Akcea’s and its Affiliates’

27

activities conducted under this Section 6.6.2(b). To the extent required to submit a regulatory filing or submission to a Regulatory Authority, Akcea shall grant or cause to be granted to Novartis and its Affiliates or Sublicensees cross-reference rights to any relevant drug master files and other filings submitted by Akcea or its Affiliates with any Regulatory Authority

6.6.3.                  Class Generic Claims; Investigator’s Brochure. To the extent Novartis intends to make any claims in a Product label or regulatory filing that are class generic to Oligonucleotides, Akcea’s or its Affiliate’s generation 2.0 or 2.5 chemistry platform(s), Conjugate Technology, or any other Akcea technology included in a Product, Novartis will provide such claims and regulatory filings to Akcea in advance and will [***] any proposals and comments made by Akcea (or its Affiliates). Novartis will provide Akcea updated versions of the investigator’s brochure when Development of the Products results in any substantive change to the safety or risk to the Products.

To the extent Akcea or Affiliates or licensors of Akcea intends to make any claims in a label or regulatory filing that (i) is reasonably likely to [***], and (ii) are [***], or any other [***], Akcea will provide such claims and regulatory filings to Novartis in advance and will consider in good faith any proposals and comments made by Novartis (or its Affiliates).

6.7.                            Compliance. Each Party will perform its activities pursuant to this Agreement (and will use reasonable efforts to require Third Parties to perform any such activities) in compliance with good laboratory practices (GLP), good clinical practices (GCP), and good manufacturing practices (GMP), in each case as applicable under the laws and regulations of the country and the state and local government wherein such activities are conducted or which are otherwise affected.

6.8.                            Pharmacovigilance and Ionis Internal ASO Safety Database.

(a)                                 On a Product-by-Product basis and within [***] ([***]) months after Option Exercise, the Parties shall agree upon and implement procedures for the mutual exchange of adverse events reports and safety information associated with the Products. Details of the operating procedures regarding such adverse events reports and safety information exchange shall be subject to a written pharmacovigilance agreement which shall be entered into within such [***] ([***]) month period.

Safety Database. To the extent collected by Novartis and in the form in which Novartis stores such information for its own purposes, Novartis will provide Akcea with information concerning toxicology, pharmacokinetics, safety pharmacology study(ies) and adverse events related to Products licensed by Novartis under this Agreement within a reasonable period of time (but not later than [***] ([***]) calendar days after Novartis’ receipt of such information). In connection with any reported serious adverse event, Novartis will provide Akcea all serious adverse event reports within a reasonable time period of time but not later than [***] ([***]) calendar days after Novartis’ receipt of such information. In addition, with respect to Products, Novartis will provide Akcea with copies of Annual safety updates filed with each IND (e.g. DSURs or IND annual reports) and the safety sections of any final Clinical Study reports within [***] ([***]) calendar days following the date such information is filed, as applicable. Furthermore, Novartis will provide in a timely manner to Akcea supporting data that Novartis determines to be reasonably related to such safety information provided by Novartis under this Section 6.8(a) and answer in a timely manner any follow-up questions reasonably requested by Akcea or its Affiliates to the extent such data and answers are reasonably available to Novartis. All such information disclosed by Novartis to Akcea will be Novartis Confidential Information and Novartis acknowledges and agrees that Akcea will provide all such information to Ionis to enable Ionis to populate the Ionis Internal ASO Safety Database.  In addition, so long as Akcea does not disclose the identity of a Product or Novartis’ identity, Akcea may disclose any such Novartis Confidential Information to (i) Akcea’s other partners pursuant to Section 6.8(c) below if such information is regarding class generic properties of ASOs, (ii) any Third Party (other than a Regulatory Authority) that contributes to the populating of the Ionis Internal ASO Safety Database, or (iii) a Regulatory Authority. Novartis will deliver all such information to Akcea for the Ionis Internal ASO Safety Database to Akcea Therapeutics, Inc., ▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Chief Medical Officer (or to such other address/contact designated in writing by Akcea). Novartis will also cause its Affiliates and Sublicensees to comply with this Section 6.8(b).

(c)                                  From time to time, Akcea and Ionis utilize the information in the Ionis Internal ASO Safety Database to conduct analyses to keep Akcea, Ionis and their partners informed regarding class generic properties of ASOs, including with respect to safety. As such, if and when Akcea identifies safety or other related issues that may be relevant to a Product (including any potential class-related toxicity), Akcea will inform Novartis in a timely manner of such issues and, if requested allow Novartis to review such issues and conclusions and allow Novartis the opportunity to review and align on safety statement and health authority submissions in a timely manner before release.

(d)                                 During the Agreement Term, Novartis may submit written requests to Akcea for Akcea to have queries run of the Ionis Internal ASO Safety Database relevant to Products licensed to Novartis under this Agreement, and Akcea will use

*  ***Confidential Treatment Requested

31

above will be paid only once upon the first achievement of the milestone event by the applicable Product regardless of how many times such Product achieves such milestone event.

7.7.2.                  If a particular milestone event is not achieved by a Product, then upon achievement of a later milestone event by such Product the milestone event payment applicable to such earlier milestone event will also be due. For example, if Novartis proceeds directly to “[***]” without achieving the “[***],” then upon achieving the “[***]” milestone event, both the “[***]” and “[***]” milestone event payments are due.

*  ***Confidential Treatment Requested

32

by-Product basis, in each case in the amounts as follows in TABLE 5 below (the “Novartis Royalty”):

TABLE 5

Annual worldwide Net Sales will be calculated by taking the aggregate sum of Net Sales of a Product for all countries worldwide.

Novartis will pay Akcea royalties on Net Sales of Products arising from pre-Commercial sales (including, named patient and other similar programs under Applicable Laws), and Novartis will provide reports and payments to Akcea consistent with Section 7.11.1. No royalties are due on Net Sales of Products arising from compassionate use and other programs providing for the delivery of Product at no cost. The sales of Products arising from named patient, compassionate use, or other similar programs will not be considered a First Commercial Sale for purposes of calculating the Initial Payment Period.

7.8.2.                  Application of Royalty Rates. All royalties set forth under Section 7.8.1 are subject to the provisions of this Section 7.8.2, and are payable as follows:

(a)                                 Initial Payment Period.

*  ***Confidential Treatment Requested

33

(b)                                 Generic Competition During the Initial Payment Period.

Notwithstanding the foregoing, on a country-by-country and Product-by-Product basis, if at any time during the Initial Payment Period a Generic Product is sold in such country, then Novartis will pay Akcea royalties on Net Sales of Products sold by Novartis, its Affiliates or Sublicensees in such country using the royalty adjustment set forth in this Section 7.8.2(b) for such country as follows:

(i)                                    If the aggregate Net Sales of such Product in such country in any Calendar Year are between [***]% - [***]% lower as compared to the aggregate Net Sales of such Product in the last Calendar Year during which there were no Generic Products sold in such country, then, following such reduction in Net Sales, the applicable Net Sales from such country upon which royalties are calculated shall be adjusted to [***] percent ([***]%) for purposes of calculation of such royalties; or

(ii)                                If the aggregate Net Sales of such Product in such country in any Calendar Year are at least [***]% lower as compared to the aggregate Net Sales of such Product in the last Calendar Year during which there were no Generic Products sold in such country, then, following such reduction in Net Sales, the applicable Net Sales from such country upon which royalties are calculated shall be adjusted to [***] percent ([***]%) for the purpose of calculation of such royalties.

On a Product-by-Product basis, certain of the Licensed Technology Controlled by Akcea as of the date of Option Exercise that may be licensed to Novartis under Section 5.1.1 or Section 5.1.2, as the case may be, are in-licensed or were acquired by Akcea or its Affiliates under (i) the agreements with Third Party licensors or sellers listed on APPENDIX 3, or (ii) the Ionis-Akcea License Agreement (such license or purchase agreements being the “Akcea In-License Agreements”), and certain milestone, royalty payments, license maintenance fees and other payments may become payable by Akcea or its Affiliates to such Third Parties under the Akcea In-License Agreements based on the Development or Commercialization of a Product by Novartis, its Affiliates or Sublicensees. Any payment obligations arising under the Akcea In-License Agreements will be paid by [***] as [***].

(b)                                 Novartis’ Existing In-License Agreements. On a Product-by-Product basis, [***] will be solely responsible for any Third Party Obligations that become payable by Novartis or its Affiliates to Third Parties under any agreements or arrangements Novartis or its Affiliates has with such Third Parties as of the date of Option Exercise, based on the Development or Commercialization of a Product by Novartis, its Affiliate or Sublicensee under this Agreement. Any such payment obligations will be paid by [***] as [***].

*  ***Confidential Treatment Requested

7.9.2.                  New In-Licensed Akcea Core Technology Patents, Akcea Manufacturing and Analytical Patents or Akcea Product-Specific Patents.

(a)                                 New In-Licensed Akcea Core Technology Patents or Akcea Manufacturing and Analytical Patents. On a Product-by-Product basis, if, after the date of Option Exercise, Akcea obtains Third Party Patent Rights necessary to Develop, Manufacture or Commercialize a Product that would have been considered an Akcea Core Technology Patent or an Akcea Manufacturing and Analytical Patent had Akcea Controlled such Patent Rights on the Effective Date, Akcea will include such Third Party Patent Rights in the license granted to Novartis under Section 5.1.1 or Section 5.1.2 (as applicable) and any and all costs arising under such Third Party agreement as they apply to a Product will be paid solely by [***] as [***].

(b)                                 New In-Licensed Akcea Product-Specific Patents. On a Product-by-Product basis, if, after the date of Option Exercise, Akcea obtains Third Party Patent Rights necessary to Develop, Manufacture or Commercialize a Product that would have been considered an Akcea Product-Specific Patent had Akcea Controlled such Patent Rights on the Effective Date, Akcea will include such Third Party Patent Rights in the license granted to Novartis under Section 5.1.1 or Section 5.1.2 (as applicable) if [***] as [***] any and all costs arising under such Third Party agreement as they apply to Products; provided, however, if Akcea obtains any such Akcea Product-Specific Patents  as a result of [***], then Akcea will include such Third Party Patent Rights in the license granted to Novartis under Section 5.1.1 or Section 5.1.2 (as applicable) and any and all costs arising under such Third Party agreement as they apply to a Product will be paid solely by [***] as [***].

7.9.3.                  Additional IP In-License Agreements.

(a)                                 After the date of Option Exercise, on a Product-by-Product basis,  Novartis will promptly provide Akcea written notice of any Additional IP Novartis believes it has identified and Akcea or its Affiliate will have the first right, but not the obligation, to negotiate with, and obtain a license from the Third Party Controlling such Additional IP. If Akcea or its Affiliate obtains such a Third Party license, Akcea will include such Additional IP in the license granted to Novartis under Section 5.1.1 or Section 5.1.2 (as applicable), and [***] will pay any financial obligations under such Third Party agreement as [***].

(b)                                 If, however, Akcea and its Affiliates elect not to obtain such a license to such Additional IP, Akcea will so notify Novartis, and Novartis may obtain such a Third Party license and, except as set forth in Section 7.9.3(d), Novartis may offset an amount equal to [***]% of [***]

*  ***Confidential Treatment Requested

36

[***] during a Calendar Quarter paid by Novartis under such Third Party license against any [***] during the same Calendar Quarter.

(c)                                  If Akcea does not agree that certain intellectual property identified by Novartis pursuant to Section 7.9.3(a) is Additional IP under Section 7.9.3(b), Akcea will send written notice to such effect to Novartis, and the Parties will engage a mutually agreed upon independent Third Party intellectual property lawyer with expertise in the patenting of Oligonucleotides, and appropriate professional credentials in the relevant jurisdiction, to determine the question of whether or not such Third Party intellectual property is Additional IP. The determination of the Third Party expert engaged under the preceding sentence will be binding on the Parties solely for purposes of determining whether Novartis is permitted to apply the offset under Section 7.9.3(b) above. The costs of any Third Party expert engaged under this Section 7.9.3(c) will be paid by the Party against whose position the Third Party lawyer’s determination is made.

(d)                                 Notwithstanding the determination of the Third Party lawyer under Section 7.9.3(c), if a Third Party Controlling Additional IP is awarded a final judgment from a court of competent jurisdiction arising from its claim against Novartis asserting that a license to such Additional IP is necessary for Novartis to practice an invention claimed within an Orange Book Patent to Commercialize a particular Product in a particular country or Novartis and Akcea mutually agree to settle such a Third Party claim, then, on a country-by-country and Product-by-Product basis, Novartis will be permitted to, subject to Section 7.8.2(g), offset against any [***] for such Product in such country (A) [***]% of the sum of any amounts paid by Novartis to such Third Party constituting [***] or [***] (excluding any [***] or [***]) awarded by such court against Novartis based on [***] occurring after Option Exercise and prior to the date of such final judgment or such settlement, and (B) [***]% of the sum of any royalties paid by Novartis to such Third Party on such Product sold in such country under such final judgment or such settlement. In no event will Novartis have the right to offset the sum of any amounts paid by Novartis to such Third Party constituting [***] or [***].

7.9.4.                  Minimum Third Party Payments. Any Minimum Third Party Payments Novartis is obligated to pay under this Agreement will be satisfied by paying Akcea directly.

7.10.                     Invoices. If the Parties explicitly refer to this Section 7.10, for any mutually agreed work performed by Akcea and/or Akcea’s Affiliates at Novartis’ request under this Agreement (other than the Akcea Activities) after (i) the first [***] hours of Akcea’s time for any

*  ***Confidential Treatment Requested

37

[***], (ii) the first [***] hours of Akcea’s time for [***], or (iii) the first [***] hours of Akcea’s time for [***], as applicable, Novartis will reimburse Akcea for the services rendered within [***] ([***]) Business Days from the date an invoice is received by Novartis; provided that any invoiced costs are for fees or services that have been rendered by Akcea plus out-of-pocket costs incurred by Akcea. Akcea’s invoices will include Akcea’s good faith estimate of the FTE cost incurred by Akcea in performing the services and the amount of any out-of-pocket costs incurred by Akcea. Before Akcea commences work for which it intends to invoice Novartis, Novartis and Akcea will agree to a budget for the work Novartis requests Akcea to perform that will include Akcea’s good faith estimate of the FTE cost plus any out-of-pocket costs.

7.11.                     Payments.

7.11.1.           Commencement. Beginning with the Calendar Quarter in which the First Commercial Sale for a Product is made and for each Calendar Quarter thereafter, Novartis will make royalty payments to Akcea under this Agreement within [***] ([***]) calendar days following the end of each such Calendar Quarter. Each royalty payment will be accompanied by a report, summarizing Net Sales for Products during the relevant Calendar Quarter and the calculation of royalties due thereon, including country, units, sales price and the exchange rate used. If no royalties are payable in respect of a given Calendar Quarter, Novartis will submit a written royalty report to Akcea so indicating together with an explanation as to why no such royalties are payable. In addition, beginning with the Calendar Quarter in which the First Commercial Sale for a Product is made and for each Calendar Quarter thereafter, Novartis will provide Akcea with a single preliminary, non-binding Net Sales amount for the entire territory (worldwide) within [***] ([***]) Business Days after the end of the Calendar Quarter in order to provide Akcea with an indication of the approximate Net Sales for all Products that are likely to be due under the applicable royalty report pursuant to Section 7.8. Such “preliminary Net Sales” shall be provided as a courtesy estimate only and shall not be used as a basis of comparison against actual royalties due or be considered binding in any way.  For the avoidance of doubt, royalty reports and “preliminary Net Sales” hereunder are Novartis’ Confidential Information subject to the terms and conditions of this Agreement.

7.11.2.           Mode of Payment. All payments under this Agreement will be (i) payable in full in U.S. dollars, regardless of the country(ies) in which sales are made, (ii) made by wire transfer of immediately available funds to an account designated by Akcea in writing, and (iii) non-creditable (except as otherwise provided in Section 7.12) and non-refundable. All payments under this Agreement shall be made in US Dollars. Any sales incurred in a currency other than US Dollars shall be converted to the US Dollar equivalent using Novartis’ then-current standard exchange rate methodology as consistently applied in its external

*  ***Confidential Treatment Requested

38

reporting for the conversion of foreign currency sales into US Dollars. Novartis shall notify Akcea in the event of changes to this methodology. In addition, an “original invoice” will be deemed duly delivered by a Party to the other Party under this Agreement when delivered electronically to such other Party and, if so delivered electronically, will be promptly followed by delivery of a paper copy of such invoice.

7.11.3.           Records Retention. Commencing with the First Commercial Sale of a Product, Novartis will keep complete and accurate records pertaining to the Net Sale of Products for a period of [***] ([***]) months after the Quarter in which such sales occurred in accordance with Novartis Accounting Standards.

7.12.                     Audits.

7.12.1.           During the Agreement Term and for a period of [***] months thereafter, at Akcea’s expense and upon written notice to Novartis, Novartis will permit an independent certified public accountant of internationally recognized standing (the “Auditor”) appointed by Akcea and reasonably acceptable to Novartis, at reasonable times and upon reasonable notice, but in no case more than [***] per Calendar Year and not more frequently than [***] with respect to records covering any specific period of time, to examine such records as may be necessary for the sole purpose of verifying the accrual of any milestone payments, the calculation and reporting of Net Sales, and the correctness of any milestone or royalty payment made under this Agreement for any period within the preceding [***] months.

7.12.2.           As a condition to and prior to examining any of Novartis’ records, such Auditor will sign a nondisclosure agreement reasonably acceptable to Novartis in form and substance. Any and all of Novartis’ records examined by such independent certified public accountant will be deemed Novartis’ Confidential Information. Novartis and its Affiliates shall make their records available for inspection by such Auditor during regular business hours at such place or places where such records are customarily kept, upon receipt of reasonable advance notice from Akcea.

7.12.3.           Upon completion of the audit, the accounting firm will provide both Novartis and Akcea with a written audit report disclosing whether the milestone or royalty payments made by Novartis are correct or incorrect and the specific details concerning any discrepancies (“Audit Report”). Before it is considered final, Novartis shall have the right to request a further determination by such Auditor as to matters which Novartis disputes within [***] ([***]) Business Days following receipt of such Audit Report. Novartis will provide Akcea and the Auditor with a reasonably detailed statement of the grounds upon which it disputes any findings in the Audit Report and the Auditor shall undertake to complete such further determination within [***] ([***]) Business Days after the dispute notice is provided, which determination shall be limited to the disputed matters. Any matters that remain unresolved shall be resolved in accordance

*  ***Confidential Treatment Requested

with the dispute resolution procedures in Section 13.1. No Audit Report shall be considered final until conclusions are undisputed by both Parties or are otherwise conclusively determined.

7.12.4.           If, as a result of any inspection of Novartis’ books and records, it is undisputed (or later conclusively determined) that Novartis’ payments under this Agreement were more or less than the milestone or royalty amount which should have been paid, then the relevant Party will make all payments required to be made by paying the other Party the difference between such amounts to eliminate any discrepancy revealed by said inspection within [***] ([***]) Business Days of receiving the final Audit Report, with interest calculated in accordance with Section 7.14; provided, however, that any such payment by Akcea to Novartis will be in the form of a credit against future royalty payments due under Section 7.8 equal to the difference between the amounts actually paid by Novartis to Akcea and the royalty amounts Novartis should have paid Akcea. Akcea will pay for such audit, except that if Novartis is found to have underpaid Akcea by more than [***]% of the amount that should have been paid for the audited period, Novartis will reimburse Akcea the reasonable fees and expenses charged by the Auditor for the audit.

7.13.                     Taxes.

7.13.1.           Taxes on Income. Each Party alone will be solely responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be paid by Novartis or Akcea (as the case may be) levied on account of, or measured in whole or in part by reference to, the income of such Party.

7.13.2.           Indirect Taxes. All payments are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any payments, the paying Party will pay such Indirect Taxes at the applicable rate in respect of such payments following receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by the receiving Party in respect of those payments.

The Parties will issue invoices for all amounts payable under this Agreement consistent with Indirect Tax requirements and irrespective of whether the sums may be netted for settlement purposes. If such amounts of Indirect Taxes are refunded by the applicable Governmental Authority or other fiscal authority subsequent to payment, the Party receiving such refund will transfer such amount to the paying Party within [***] ([***]) Business Days of receipt. The Parties agree to reasonably cooperate to provide any information required by the Party pursuing a refund of Indirect Taxes paid.

7.13.3.           Withholding Tax. To the extent the paying Party is required to deduct and withhold taxes on any payment, the paying Party will pay the amounts of such taxes to the proper Governmental Authority for the account of the receiving Party and remit the net amount to the receiving Party in a timely manner. The paying Party will promptly furnish the receiving Party with proof of payment

of such taxes. If documentation is necessary in order to secure an exemption from, or a reduction in, any withholding taxes, the Parties will provide such documentation to the extent they are entitled to do so.

7.13.4.           Tax Cooperation. At least [***] ([***]) Business days prior to the date a given payment is due under this Agreement, the non-paying Party will provide the paying Party with any and all tax forms that may be reasonably necessary in order for the paying Party to lawfully not withhold tax or to withhold tax at a reduced rate with respect to such payment under an applicable bilateral income tax treaty. Following the paying Party’s timely receipt of such tax forms from the non-paying Party, the paying Party will not withhold tax or will withhold tax at a reduced rate under an applicable bilateral income tax treaty, if appropriate under the Applicable Laws. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Law, of withholding taxes resulting from payments made under this Agreement, such recovery to be for the benefit of the Party who would have been entitled to receive the money but for the application of withholding tax under this Section 7.13.

The provisions of this Section 7.13 are to be read in conjunction with the provisions of Section 13.4 below.

7.14.                     Interest. Any undisputed payments to be made hereunder that are not paid on or before the date such payments are due under this Agreement, and any payments that are pending resolution of any dispute unless the dispute is ruled in favor of the paying Party, will bear interest at a rate per annum equal to the lesser of (i) the rate announced by Bank of America (or its successor) as its prime rate in effect on the date that such payment would have been first due plus [***]% or (ii) the maximum rate permissible under applicable law.

8.1.                            Joint Patent Committee.

8.1.1.                  Unless the Parties mutually agree to establish it sooner, the Parties will establish a “Joint Patent Committee” or “JPC” upon the [***]. The JPC will serve as the primary contact and forum for discussion between the Parties with respect to intellectual property matters arising under this Agreement, and will cooperate with respect to the activities set forth in this Section 8.1. If the JPC dissolves, each Party may designate a patent attorney who will be responsible for intellectual property matters under this Agreement. A strategy will be discussed with regard to (i) prosecution and maintenance, defense and enforcement of Akcea Product-Specific Patents that would be or are licensed to Novartis under Section 5.1 and Novartis Product-Specific Patents, (ii) defense against allegations of infringement of Third Party Patent Rights, (iii) licenses to Third Party Patent Rights or Know-How, and

*  ***Confidential Treatment Requested

41

(iv) the timing and subject matter of any potential publications regarding a Product, in each case to the extent such matter would be reasonably likely to have a material impact on this Agreement or the licenses granted hereunder, which strategy will be considered in good faith by the Party entitled to prosecute, enforce and defend such Patent Rights, as applicable, hereunder, but will not be binding on such Party. Upon Novartis’ exercise of (or the expiration or termination of) the last Option, each Party will no longer have the obligation, but will continue to have the right, to participate in the JPC, provided that, if requested by Novartis, Akcea shall consider in good faith and not unreasonably refuse to participate in the JPC.

8.1.2.                  The JPC will comprise an equal number of at most three members from each Party. The JPC will meet as often as agreed by them (and at least semi-Annually), to discuss matters arising out of the activities set forth in this Section 8.1. The JPC will determine the JPC operating procedures at its first meeting, including the JPC’s policies for replacement of JPC members, and the location of meetings, which will be codified in the written minutes of the first JPC meeting. The Parties may escalate issues to the Executives for input and resolution pursuant to Section 13.1. Each Party’s representatives on the JPC will consider comments and suggestions made by the other in good faith. Each Party will bear their own cost of participation on the JPC.

8.2.                            Ownership.

8.2.1.                  Akcea Technology and Novartis Technology. As between the Parties, Akcea will own and retain all of its rights, title and interest in and to the Licensed Know-How and Licensed Patents and Novartis will own and retain all of its rights, title and interest in and to the Novartis Know-How and Novartis Patents, subject to any rights or licenses expressly granted by one Party to the other Party under this Agreement.

8.2.2.                  Program Technology. As between the Parties, Novartis is the sole owner of any Know-How discovered, invented or created solely by or on behalf of Novartis or its Affiliates under or in connection with this Agreement (“Novartis Program Know-How”) and any Patent Rights that claim or cover Novartis Program Know-How (“Novartis Program Patents” and together with the Novartis Program Know-How, the “Novartis Program Technology”), and will retain all of its rights, title and interest thereto, subject to any rights or licenses expressly granted by Novartis to Akcea under this Agreement. As between the Parties, Akcea is the sole owner of any Know-How discovered, invented or created solely by or on behalf of Akcea or its Affiliates under or in connection with this Agreement (“Akcea Program Know-How”) and any Patent Rights that claim or cover such Know-How (“Akcea Program Patents” and together with the Akcea Program Know-How, the “Akcea Program Technology”), and will retain all of its rights, title and interest thereto, subject to any rights or licenses expressly granted by Akcea to Novartis under this Agreement. Any Know-How discovered, invented or created jointly under or

in connection with this Agreement by or on behalf of both Parties or their respective Affiliates or Third Parties acting on their behalf (“Jointly-Owned Program Know-How”), and any Patent Rights that claim or cover such Jointly-Owned Program Know-How (“Jointly-Owned Program Patents”, and together with the Jointly-Owned Program Know-How, the “Jointly-Owned Program Technology”), are owned jointly by Novartis and Akcea on an equal and undivided basis, including all rights, title and interest thereto, subject to any rights or licenses expressly granted by one Party to the other Party under this Agreement.

Except as expressly provided in this Agreement, neither Party will have any obligation to account to the other for profits with respect to, or to obtain any consent of the other Party to license or exploit, Jointly-Owned Program Technology by reason of joint ownership thereof, and each Party hereby waives any right it may have under the laws of any jurisdiction to require any such consent or accounting. Furthermore, the Parties acknowledge and agree that any such Jointly-Owned Program Technology is [***], and therefore shall not be [***] under this Agreement. The Parties acknowledge and agree that either Party may freely utilize or otherwise exploit any Jointly-Owned Program Technology without recourse, accounting or any other obligations to the other Party. This right includes the right to grant sublicenses or otherwise dispose of the Party’s interest in any Jointly-Owned Program Technology, subject to the following limitations. If either Party (“Offering Party”) intends to grant a license, assign or otherwise dispose of its rights in any [***] to a Third Party under such Party’s interest in such [***] for the development and/or commercialization of a Product, the Offering Party will first provide the other Party notice of such intent and offer to such Party a right of first negotiation together with proposed terms for such a license (a “ROFN Notice”). Such Party will have [***] calendar days from the date such Party receives a ROFN Notice to send notice to the Offering Party of such Party’s desire to exercise its right of first negotiation (a “Negotiation Notice”). If (i) such Party does not timely deliver a Negotiation Notice to the Offering Party, or (ii) such Party timely delivers a Negotiation Notice to the Offering Party but the Parties cannot agree on the terms of such a license by the [***] calendar day after the date the Offering Party receives such Negotiation Notice, then the Offering Party may grant a license to a Third Party under such Offering Party’s interest in such [***] for the development and/or commercialization of a Product on terms [***].

Each Party will promptly disclose to the other Party in writing, and will cause its Affiliates to so disclose, the discovery, invention or creation of any Novartis Program Technology, Akcea Program Technology or Jointly-Owned Program

8.2.3.                  In addition, the JPC (or the Parties’ respective patent representatives if no JPC exists) will be responsible for the assessment of inventorship of Program Patents in accordance with United States patent laws. In case of a dispute in the JPC (or otherwise between Akcea and Novartis) over inventorship of Program Patents, if the JPC (or the Parties’ respective patent representatives if no JPC exists) cannot resolve such dispute, such dispute will be resolved by independent patent counsel not engaged or regularly employed in the past two years by either Party (or its Affiliates) and reasonably acceptable to both Parties. The decision of such independent patent counsel will be binding on the Parties. Expenses of such patent counsel will be shared equally by the Parties.

8.3.                            Filing, Prosecution and Maintenance of Patents.

8.3.1.                  Licensed Patents.

(a)                                 Akcea Core Technology Patents and Akcea Manufacturing and Analytical Patents. Akcea will control and be responsible for Prosecuting and Maintaining (i) the Akcea Core Technology Patents, and (ii) Akcea Manufacturing and Analytical Patents, including any Jointly-Owned Program Patents in (i) or (ii).

(b)                                 Akcea Product-Specific Patents. Prior to the date Novartis exercises its Option for a Product in accordance with this Agreement, Akcea will control and be responsible for Prosecuting and Maintaining the Akcea Product-Specific Patents (including any Jointly-Owned Program Patents that are Product-Specific Patents). On a Product-by-Product basis, following the date Novartis exercises its Option for such Product in accordance with this Agreement (and so long as the applicable license to Novartis under Section 5.1 is in effect), Akcea will continue to control and be responsible for Prosecuting and Maintaining the Akcea Product-Specific Patents (including any Jointly-Owned Program Patents that are Product-Specific Patents) that (i) Cover an Akcea-Separate Product or (ii) Cover Conjugate Technology (“Akcea Special Product-Specific Patents”) and Novartis will control and be responsible for Prosecuting and Maintaining all other Product-Specific Patents (including any Jointly-Owned Program Patents) that are not Akcea Special Product-Specific Patents.

(c)                                  Other Jointly-Owned Program Patents. The Parties will decide through

*  ***Confidential Treatment Requested

44

the JPC the appropriate Party to control and be responsible for Prosecuting and Maintaining all other Jointly-Owned Program Patents not provided for above.

8.3.2.                  Other Matters Pertaining to Prosecution and Maintenance of Patents.

(a)                     Each Party will keep the other Party informed through the JPC as to material developments with respect to the Prosecution and Maintenance of the Product-Specific Patents or Jointly-Owned Program Patents for which such Party has responsibility for Prosecution and Maintenance pursuant to Section 8.3.1 or this Section 8.3.2, including by providing copies of any office actions or office action responses or other correspondence that such Party provides to or receives from any patent office, including notice of all interferences, reissues, re-examinations, inter partes reviews, post-grant reviews, oppositions or requests for patent term extensions, and all patent-related filings, and by providing the other Party the timely opportunity to have reasonable input into the strategic aspects of such Prosecution and Maintenance.

(b)                     If Novartis elects (i) not to file and prosecute patent applications for a Patent Right Novartis is responsible for Prosecuting and Maintaining under Section 8.3.1 above (“Novartis-Prosecuted Patents”) in a particular country, (ii) not to continue the prosecution (including any interferences, oppositions, reissue proceedings, re-examinations, and patent term extensions, adjustments, and restorations) or maintenance of any Novartis-Prosecuted Patent in a particular country, or (iii) not to file and prosecute patent applications for the Novartis-Prosecuted Patent in a particular country following a written request from Akcea to file and prosecute in such country, then Novartis will so notify Akcea promptly in writing of its intention (including a reasonably detailed rationale for doing so) in good time to enable Akcea to meet any deadlines by which an action must be taken to establish or preserve any such Patent Right in such country; and Akcea will have the right, but not the obligation, to file, prosecute, maintain, enforce, or otherwise pursue such Novartis-Prosecuted Patent in the applicable country at its own expense with counsel of its own choice. In such a case, Novartis will cooperate with Akcea to file for, or continue to Prosecute and Maintain or enforce, or otherwise pursue such Novartis-Prosecuted Patent in such country in Akcea’s own name, but only to the extent that Novartis is not required to take any position with respect to such abandoned Novartis-Prosecuted Patent that would be reasonably likely to adversely affect the scope, validity or enforceability of any of the other Patent Rights being prosecuted and maintained by Novartis under this Agreement. Notwithstanding anything to the contrary in this Agreement, if Akcea assumes responsibility for the Prosecution and Maintenance of any such Novartis-Prosecuted Patent under this Section 8.3.2(b), Akcea will have no obligation to notify Novartis if Akcea intends

45

to abandon such Novartis-Prosecuted Patent.

(c)                      The Parties, through the JPC, will cooperate in good faith to determine if and when any divisional or continuation applications will be filed with respect to any Jointly-Owned Program Patents or Product-Specific Patents, and where a divisional or continuation patent application filing would be practical and reasonable, then such a divisional or continuation filing will be made.

(d)                     If the Party responsible for Prosecution and Maintenance pursuant to Section 8.3.1 intends to abandon a Jointly-Owned Program Patent without first filing a continuation or substitution, then such Party will notify the other Party of such intention at least [***] ([***]) calendar days before such Jointly-Owned Program Patent will become abandoned, and such other Party will have the right, but not the obligation, to assume responsibility for the Prosecution and Maintenance thereof at its own expense (subject to Section 8.4) with counsel of its own choice, in which case the abandoning Party will, and will cause its Affiliates to, assign to the other Party (or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, title and interest in and to such Jointly-Owned Program Patents. If a Party assumes responsibility for the Prosecution and Maintenance of any such Jointly-Owned Program Patents under this Section 8.3.2(d), such Party will have no obligation to notify the other Party of any intention of such Party to abandon such Jointly-Owned Program Patents.

8.4.                            Patent Costs. Except as set forth in Section 8.3.2 and this Section 8.4, each Party will be responsible for all Patent Costs incurred by such Party prior to and after the Effective Date in all countries designated by it in the Prosecution and Maintenance of Patent Rights for which such Party is responsible under ARTICLE 8. Unless the Parties agree otherwise, the following Patent Costs will be paid by the Parties as follows:

8.4.1.                  Akcea and Novartis will [***] the Patent Costs associated with the Prosecution and Maintenance of each Akcea Special Product-Specific Patent with each Party’s share of such Patent Costs calculated based on the [***]; and

8.4.2.                  Akcea and Novartis will [***] the Patent Costs associated with the Prosecution and Maintenance of Jointly-Owned Program Patents;

provided that, either Party may decline to pay its share of costs for filing, prosecuting and maintaining any Akcea Special Product-Specific Patents or Jointly-Owned Program Patents in a particular country or particular countries, in which case the declining Party will, and will cause its Affiliates to, assign to the other Party (or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, titles and interests in and to such Akcea Special

*  ***Confidential Treatment Requested

8.5.1.                  AKCEA-APO(a)-LRx and AKCEA-APOCIII-LRx – Prior to Option Exercise. If a Third Party initiates a Proceeding claiming a Patent Right owned by or licensed to such Third Party is infringed by the Development, Manufacture or Commercialization of any Product with respect to which Novartis has not yet exercised its Option, Akcea will have the first right, but not the obligation, to defend against any such Proceeding at its sole cost and expense. If Akcea elects to defend against such Proceeding, then Akcea will have the sole right to direct the defense and to elect whether to settle such claim.

8.5.2.                  AKCEA-APO(a)-LRx and AKCEA-APOCIII-LRx – After Option Exercise. If a Third Party initiates a Proceeding claiming a Patent Right owned by or licensed to such Third Party is infringed by the Development, Manufacture or Commercialization of any Product being Developed or Commercialized by Novartis under a license granted under Section 5.1, then Novartis will have the first right, but not the obligation, to defend against any such Proceeding at its sole cost and expense. If Novartis elects to defend against such Proceeding, then Novartis will have the sole right to direct the defense and to elect whether to settle such claim (but only with the prior written consent of Akcea, not to be unreasonably withheld, conditioned or delayed). Akcea will reasonably assist Novartis in defending such Proceeding and cooperate in any such litigation at Novartis’ request and expense. Novartis will keep Akcea apprised of the progress of such Proceeding. If Novartis elects not to defend against a Proceeding, then Novartis will so notify Akcea in writing within [***] ([***]) calendar days after Novartis first receives written notice of the initiation of such Proceeding, and Akcea will have the right, but not the obligation, to defend against such a Proceeding at its sole cost and expense and thereafter Akcea will have the sole right to direct the defense thereof, including the right to settle such claim (but only with the prior written consent of Novartis, which consent will not be unreasonably withheld, delayed or conditioned). In any event, the Party not defending such Proceeding will reasonably assist the other Party and cooperate in any such litigation at defending Party’s request and expense. Each Party may at its own expense and with its own counsel join any defense initiated or directed by the other Party under this Section 8.5. Each Party will provide the other Party with prompt written notice of the commencement of any such Proceeding under this Section 8.5, and such Party will promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party.

8.5.3.                  Interferences, Reissues, Re-Examinations and Oppositions. If a Third Party initiates a Proceeding related to an interference, reissue, re-examination or opposition of an Akcea Product-Specific Patent, then (A) if such Proceeding

*  ***Confidential Treatment Requested

47

occurs prior to Option exercise (or after Option exercise with respect to an Akcea Special Product-Specific Patent), Akcea will have the right, but not the obligation, to control the defense of such Proceeding as Akcea determines in Akcea’s sole discretion, and (B) if such Proceeding occurs after Option exercise and does not involve an Akcea Special Product-Specific Patent, Novartis will, at Novartis’ expense, by written notice to Akcea either (i) control the defense of such Proceeding solely to the extent such Proceeding relates to an interference, reissue, re-examination or opposition of an Akcea Product-Specific Patent that is not an Akcea Special Product-Specific Patent, or (ii) have Akcea control the defense of such Proceeding, provided if Novartis makes no such election within a reasonable period of time, then Akcea will have the right, but not the obligation, to control the defense of such Proceeding and Akcea and Novartis will evenly split the cost of such defense. If Akcea elects not to defend against such a Proceeding under (A) in this section above, then Akcea will so notify Novartis in writing within [***] ([***]) calendar days after Akcea first receives written notice of the initiation of such Proceeding, and Novartis will have the right, but not the obligation, to defend against such Proceeding at its sole cost and expense and thereafter Novartis will have the sole right to direct the defense thereof, including the right to settle such claim (but only with the prior written consent of Akcea, which consent will not be unreasonably withheld, delayed or conditioned). In any event, the Party not defending such Proceeding will reasonably assist the other Party and cooperate in any such litigation at the defending Party’s request and expense. Each Party may at its own expense and with its own counsel join any defense initiated or directed by the other Party under this Section 8.5. Each Party will provide the other Party with prompt written notice of the commencement of any such Proceeding under this Section 8.5, and such Party will promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party.

8.6.                            Enforcement of Patents Against Competitive Infringement. With respect to infringement, unauthorized use, misappropriation or threatened infringement by a Third Party of any Akcea Product-Specific Patents by reason of the development, manufacture, use or commercialization of a product that binds to an Exclusive Target (“Competitive Infringement”), prior to the date Novartis exercises its applicable Option under this Agreement (or after Option exercise with respect to an Akcea Special Product-Specific Patent), Akcea will have the sole right, but not the obligation, to institute, prosecute, and control a Proceeding with respect thereto. With respect to any Competitive Infringement involving an Akcea Licensed Patent that is not an Akcea Special Product-Specific Patent that occurs after the date Novartis exercises its applicable Option under this Agreement, the Parties will handle such Competitive Infringement in accordance with the remainder of this Section 8.6.

8.6.1.                  Duty to Notify of Competitive Infringement. If either Party learns of a Competitive Infringement by a Third Party, such Party will promptly notify the other Party in writing and will provide such other Party with available evidence

8.6.2.                  Control of Competitive Infringement Proceedings. For any Competitive Infringement involving an Akcea Product-Specific Patent that is not an Akcea Special Product-Specific Patent for a Product licensed to Novartis under Section 5.1 that occurs after Novartis exercises its Option for such Product, so long as part of such Proceeding Novartis also enforces any Patent Rights Controlled by Novartis being infringed that Cover such Product, then Novartis will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding with respect thereto by counsel of its own choice at its own expense, and Akcea will have the right, at its own expense, to be represented in that action by counsel of its own choice, however, Novartis will have the right to control such litigation. If Novartis fails to initiate a Proceeding within a period of [***] ([***]) calendar days after receipt of written notice of such Competitive Infringement (subject to a [***] ([***]) calendar days extension to conclude negotiations, if Novartis has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such [***] calendar day period), Akcea will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice, and Novartis will have the right to be represented in any such action by counsel of its own choice at its own expense.

8.6.3.                  Joinder; Cooperation.

49

Proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); then

(b)                                 any remaining proceeds will be allocated as follows: (A) prior to Option exercise, to [***], and (B) after Option exercise, (x) if Novartis initiates or controls the defense of the Proceeding pursuant to Section 8.5.2 or Section 8.6.2, [***], or (y) if Akcea initiates or controls the defense of the Proceeding, [***] will receive and retain the remaining proceeds.

8.6.5.                  Settlement. Notwithstanding anything to the contrary in this ARTICLE 8, neither Party may enter a settlement, consent judgment or other voluntary final disposition of a suit under this ARTICLE 8 that disclaims, limits the scope of, admits the invalidity or unenforceability of, or grants a license, covenant not to ▇▇▇ or similar immunity under a Patent Right Controlled by the other Party without first obtaining the written consent of the Party that Controls the relevant Patent Right.

8.6.6.                  35 USC 271(e)(2) Infringement. Notwithstanding anything to the contrary in this Section 8.6, for a Competitive Infringement under 35 USC 271(e)(2), the time period set forth in Section 8.6.2 during which a Party will have the initial right to bring a Proceeding will be shortened to a total of twenty five (25) calendar days, so that, to the extent the other Party has the right, pursuant to such Section to initiate a Proceeding if the first Party does not initiate a Proceeding, such other Party will have such right if the first Party does not initiate a Proceeding within [***] ([***]) calendar days after such first Party’s receipt of written notice of such Competitive Infringement.

8.7.                            Other Infringement - Jointly-Owned Program Patents. With respect to the infringement of a Jointly-Owned Program Patent which is not a Competitive Infringement, the Parties will cooperate in good faith to bring suit together against such infringing party or the Parties may decide to permit one Party to solely bring suit. Any damages or other monetary awards recovered with respect to a Proceeding brought pursuant to this Section 8.7 will be shared as follows: (i) the amount of such recovery will first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such Proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); (ii) (A) if the Parties jointly initiate a Proceeding pursuant to this Section 8.7, each Party will retain or receive 50% of such remaining proceeds; and (B) if only one Party initiates the Proceeding pursuant to this Section 8.7, such Party will retain or receive such remaining proceeds.  Notwithstanding the provision of Section 8.6.4. the remaining proceeds contemplated under this section, if retained by Novartis, shall not be treated as if it were Net Sales,

Notwithstanding the preceding sentence, Novartis will retain final decision-making authority as to [***] for a Product that [***], regardless of which Party owns such [***].

8.9.                            Joint Research Agreement under the ▇▇▇▇▇-▇▇▇▇▇ America Invents Act. If a Party intends to invoke its rights under 35 U.S.C. § 102(c) of the ▇▇▇▇▇-▇▇▇▇▇ America Invents Act, it will notify the other Party and neither Party will make an election under such provision when exercising its rights under this ARTICLE 8 without the prior written consent of the other Party (such consent not to be unreasonably withheld, conditioned or delayed), and the Parties will use reasonable efforts to cooperate and coordinate their activities with such Party with respect to any submissions, filings or other activities in support thereof. The Parties acknowledge and agree that this Agreement is a “joint research agreement” as defined in 35 U.S.C. § 100(h).

8.10.                     Obligations to Third Parties. Notwithstanding any of the foregoing, each Party’s rights and obligations with respect to Licensed Technology under this ARTICLE 8 will be subject to the restrictions set forth in Section 5.5, provided, however, that, to the extent that Akcea has a non-transferable right to prosecute, maintain or enforce any Patent Rights licensed to Novartis hereunder and, this Agreement purports to grant any such rights to Novartis, Akcea will act in such regard with respect to such Patent Rights at Novartis’ direction.

8.11.                     Additional Rights and Exceptions. Other than as set forth in this ARTICLE 8, Akcea retains the sole right to (i) commence, control, prosecute and settle any Proceeding involving Volanesorsen, and (ii) Prosecute and Maintain (A) Akcea Special Product-Specific Patents, (B) Akcea Core Technology Patents, and (C) Akcea Manufacturing and Analytical Patents during the Agreement Term and to control any enforcement of Akcea Special Product-Specific Patents, Akcea Core Technology Patents and Akcea Manufacturing and Analytical Patents, and will take the lead on such enforcement solely to the extent that the scope or validity of any Patent Rights Controlled by Akcea and Covering Akcea Special Product-Specific Patents, the Akcea Core Technology Patents or Akcea Manufacturing and Analytical Patents is at risk.

ARTICLE 10.
INDEMNIFICATION; INSURANCE

10.1.                     Indemnification by Novartis. Novartis agrees to defend Akcea, its Affiliates and their respective directors, officers, employees and their respective successors, heirs and assigns (collectively, the “Akcea Indemnitees”), and will indemnify and hold harmless the Akcea Indemnitees, from and against any liabilities, losses, costs, damages, fees or expenses

57

payable to a Third Party, and reasonable attorneys’ fees and other legal expenses with respect thereto (collectively, “Losses”) arising out of any claim, action, lawsuit or other proceeding by a Third Party (collectively, “Third Party Claims”) brought against any Akcea Indemnitee and resulting from or occurring as a result of: (a) any activities conducted by a Novartis employee, consultant, Affiliate, Sublicensee, or (sub)contractor in the performance of the activities Novartis agrees to perform under this Agreement, including, the Manufacture, Development or Commercialization of any Product, or (b) any breach by Novartis of any of its representations, warranties or covenants pursuant to this Agreement; except in any such case to the extent such Losses result from: (i) the negligence or willful misconduct of any Akcea Indemnitee, (ii) any breach by Akcea of any of its representations, warranties, covenants or obligations pursuant to this Agreement, or (iii) any breach of Applicable Law by any Akcea Indemnitee, and provided that Novartis shall not be obliged to so indemnify, defend and hold harmless the Akcea Indemnities for any claims for which Akcea has an obligation to indemnify Novartis Indemnities pursuant to Section 10.2.

10.2.                     Indemnification by Akcea. Akcea agrees to defend Novartis, its Affiliates and their respective directors, officers, employees and their respective successors, heirs and assigns (collectively, the “Novartis Indemnitees”), and will indemnify and hold harmless the Novartis Indemnitees, from and against any Losses arising out of Third Party Claims brought against any Novartis Indemnitee and resulting from or occurring as a result of: (a) any activities that an Akcea employee, consultant, Affiliate, Sublicensee, or (sub)contractor has undertaken in respect of Products either prior to the Effective Date or outside the scope of this Agreement, or in the performance of the activities Akcea agreed to perform under this Agreement, including, the Manufacture, Development or Commercialization of any Product or Terminated Product, or (b) any breach by Akcea of any of its representations, warranties or covenants pursuant to this Agreement; except in any such case to the extent such Losses result from: (i) the negligence or willful misconduct of any Novartis Indemnitee, (ii) any breach by Novartis of any of its representations, warranties, covenants or obligations pursuant to this Agreement, or (iii) any breach of Applicable Law by any Novartis Indemnitee, and provided that Akcea  shall not be obliged to so indemnify, defend and hold harmless the Novartis Indemnities for any claims for which Novartis has an obligation to indemnify Akcea Indemnities pursuant to Section 10.1.

10.3.                     Notice of Claim.  All indemnification claims provided for in Section 10.1 or Section 10.2 will be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party will give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under Section 10.1 or Section 10.2, but in no event will the indemnifying Party be liable for any Losses to the extent such Losses result from any delay in providing such notice. The failure or delay to so notify the Indemnified Party shall not relieve the indemnifying Party of any obligation or liability to the Indemnified Party, except to the extent that the indemnifying Party demonstrates that its ability to defend or resolve such Claim is adversely affected as a result of such failure or delay.  Each Indemnification Claim Notice must contain a

58

description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received or sent in respect of any Losses and Third Party Claims.

10.4.                     Defense, Settlement, Cooperation and Expenses.

10.4.1.           Control of the Defense. At its option, the indemnifying Party may assume the defense and handling of any Third Party Claim by giving written notice to the Indemnified Party within [***] ([***]) calendar days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption and handling of the defense of a Third Party Claim by the indemnifying Party shall not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. If the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will as soon as is reasonably possible deliver to the indemnifying Party all original notices and documents (including court papers) received or sent by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in this Section 10.4.1, the Indemnified Party will be responsible for the legal costs or expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim.

10.4.2.           Right to Participate in Defense. Without limiting Section 10.4.1, any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnified Party’s own cost and expense unless (a) the employment thereof has been specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 10.4.1 (in which case the Indemnified Party will control the defense), or (c) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles in which case the indemnifying Party will be responsible for any such costs and expenses of counsel for the Indemnified Party.

10.4.3.           Settlement. With respect to any Third Party Claims relating solely to the payment of money damages in connection with a Third Party Claim and that will not admit liability or violation of Law on the part of the Indemnified Party or result in the Indemnified Party’s becoming subject to injunctive or other

*  ***Confidential Treatment Requested

59

relief or otherwise adversely affecting the business of the Indemnified Party in any manner (such as granting a license or admitting the invalidity of a Patent Right Controlled by an Indemnified Party), and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 10.4.1, the indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld, delayed or conditioned). The indemnifying Party will not be liable for any settlement, consent to entry of judgment, or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned.

10.4.4.           Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket costs and expenses in connection therewith.

10.4.5.           Costs and Expenses. Except as provided above in this Section 10.4, the costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

60

10.5.                     Insurance.

10.5.1.           Akcea’s Insurance Obligations. Akcea will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement, including its indemnification obligations herein, in such amounts and on such terms as are customary for prudent practices for biotech companies of similar size and with similar resources in the pharmaceutical industry for the activities to be conducted by it under this Agreement taking into account the scope of development of Products.

10.5.2.           Novartis’ Insurance Obligations. Novartis hereby represents and warrants to Akcea that it will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement (including product liability), including its indemnification obligations herein, in such amounts and on such terms as are customary for prudent practices for large companies in the pharmaceutical industry for the activities to be conducted by Novartis under this Agreement.

10.6.                     LIMITATION OF CONSEQUENTIAL DAMAGES. EXCEPT FOR (A) THIRD PARTY CLAIMS THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 10, (B) CLAIMS ARISING OUT OF A PARTY’S WILLFUL MISCONDUCT OR FRAUD UNDER THIS AGREEMENT, (C) A PARTY’S BREACH OF ARTICLE 4, (D) NOVARTIS’ BREACH OF SECTION 6.5, OR (E) CLAIMS ARISING OUT OF A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS UNDER THIS AGREEMENT, NEITHER PARTY NOR ANY OF ITS AFFILIATES WILL BE LIABLE TO THE OTHER PARTY TO THIS AGREEMENT OR ITS AFFILIATES FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR OTHER INDIRECT DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

ARTICLE 11.
TERM; TERMINATION

11.1.                     Agreement Term; Expiration. This Section 11.1, ARTICLE 12 and ARTICLE 13 of this Agreement are effective as of the Execution Date and the remainder of this Agreement will become effective as of the Effective Date and, unless earlier terminated pursuant to the other provisions of this ARTICLE 11, will continue in full force and effect until this Agreement expires as follows:

61

11.1.1.           where all Options have expired unexercised;

11.1.2.           on a country-by-country and Product-by-Product basis, on the date of expiration of all payment obligations by Novartis under this Agreement with respect to such Product in such country; or

The period from the Effective Date until the date of expiration of this Agreement pursuant to this Section 11.1 or earlier termination of this Agreement pursuant to Section 11.2, is the “Agreement Term.” If the Effective Date has not occurred by the [***] calendar day after the Execution Date, then either Party will have the right to terminate this Agreement, including this Section 11.1, ARTICLE 12 and ARTICLE 13, with immediate effect by providing written notice of such termination to the other Party. If by the [***] calendar day after the Execution Date, the Parties anticipate that the Effective Date may not occur by the [***] calendar day after the Execution Date, within [***] calendar days upon receiving written notice, the Parties will promptly meet to discuss in good faith any additional actions or amendments to the Agreement the Parties may take or agree upon to cause the Effective Date to occur as soon as reasonably practicable.

If the breach is curable, Akcea will have [***] ([***]) calendar days to cure such breach.

relevant part on a Product-by-Product basis if such breach does not relate to this Agreement in its entirety, by providing written notice to Akcea.

(b)                                 Akcea’s Right to Terminate.

If the breach is curable, Novartis will have [***] ([***]) calendar days to cure such breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [***] ([***]) calendar days following such notice).

Following such a meeting, if Akcea fails to use Commercially Reasonable Efforts as contemplated in ARTICLE 1 and such failure constitutes a material breach of this Agreement, then subject to Section 11.2.4 below, Novartis will have the right, at its sole discretion, to terminate this Agreement in whole or in part on a Product-by-Product basis.

Industry-recognized principles of both inclusion of authors and order of authors will be applied to respect appropriately the contributions of all parties to the inventions or data being presented or published. For abstract, presentation or publication that are authored or co-authored with Akcea according to the preceding sentence, each Party will review such proposed publication in order to avoid the unauthorized disclosure of a Party’s Confidential Information and to preserve the patentability of inventions arising under this Agreement. Each Party will first submit to the other Party an early draft of all such publications or presentations, whether they are to be presented orally or in written form, at least [***] ([***]) Business Days prior to submission for publication including to facilitate the publication of any summaries of Clinical Studies data and results as required on the clinical trial registry of each respective Party. If at any time during such [***] ([***]) Business Day period, the other Party informs such Party that its proposed publication discloses inventions made by either Party under this Agreement that have not yet been protected through the filing of a patent application, or the public disclosure of such proposed publication could be expected to have a material adverse effect on any Patent Rights or Know-How solely owned or Controlled by such other Party, then such Party will either (i) delay such proposed publication for up to [***] ([***]) calendar days from the date the other Party informed such Party of its objection to the proposed publication, to permit the timely preparation and first filing of patent

12.4.6.           SEC Filings.

Notwithstanding the foregoing, to the extent information regarding this Agreement or a Product has already been publicly disclosed, either Party (or its Affiliates) may subsequently disclose the same information to the public without the consent of the other Party.

12.4.8.           Acknowledgment. Novartis will acknowledge in any press release, public presentation or publication regarding a Product, Akcea’s and/or Ionis’ role in discovering and developing the Product, that the Product is under license from Akcea and otherwise acknowledge Akcea’s contributions, and Akcea’s and, if referring to Ionis or Akcea as an Affiliate of Ionis, Ionis’ and Akcea’s stock ticker symbol (e.g., Nasdaq: IONS).

13.1.4.           Arbitration.

(a)                                 If the Parties cannot resolve the Dispute through Escalation, and a Party desires to pursue resolution of the Dispute, any Dispute will be finally settled under the Rules of Arbitration of the ICC by a panel of three arbitrators appointed in accordance with said Rules, provided however, that the third arbitrator, who will act as president of the arbitral tribunal, will not be appointed by the International Court of Arbitration, but by the two arbitrators which have been appointed by either of the Parties in accordance with Article 12 para 4 of said Rules.

(b)                                 The place of arbitration will be New York, New York and the language to be used in any such proceeding (and for all testimony, evidence and written documentation) will be English.

The Parties agree to select the arbitrator(s) within [***] ([***]) calendar days after initiation of the arbitration. The hearing will be concluded within [***] ([***]) calendar days after selection of the arbitrator(s) and the award will be rendered within [***] calendar days after the conclusion of the hearing, or of any post hearing briefing, which briefing will be completed by both Parties within [***] ([***]) calendar days after the conclusion of the hearing.

Subject to the terms of this Agreement, this Agreement will be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Unless explicitly agreed otherwise in writing between the Parties, if any assignment of this Agreement or of any rights or obligations under this Agreement results in higher withholding taxes compared to the withholding taxes applicable prior to such assignment, then such higher withholding taxes will be borne by the assigning Party (“Transferring Party”) such that the Party (“Non-Transferring Party”) entitled to receive a given payment under this Agreement receives the amount of such payment such Party would have otherwise received under this Agreement but for the assigning Party’s transfer or assignment. Any purported assignment or transfer made in contravention of this Section 13.4 will be null and void.

Within [***] ([***]) calendar days following the closing of such Change of Control Event, the Party or the Acquirer will meet or hold a teleconference with the other Party at a mutually agreed date, time and/or place to discuss any possible impacts of the Change of Control Event for this Agreement. In the event of a change of control involving Akcea, within [***] calendar days following the announcement of a Change of Control Event, Novartis, Akcea and Ionis shall meet and negotiate in good faith any amendment required to this Agreement reflecting obligations that may have been assumed by Ionis on behalf of Akcea and rights that may be owned by Ionis but that may be required for Novartis to fully exercise the licenses granted under this Agreement.

78

Agreement. Each Party will be responsible for any income or non-income taxes that arise as a result of such Party’s use of any Third Party subcontractors hereunder, including payroll, income, withholding, sales and use, VAT, customs, duties excise or property taxes, and such taxes will not be reimbursable expenditures.

In addition, Novartis will use Commercially Reasonable Efforts to include in agreements with CMOs, the [***] in the event the applicable Option is terminated, expires unexercised or this Agreement is terminated.

13.8.                     Force Majeure. No Party will be held responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure means a cause beyond the reasonable control of a Party, which may include acts of God, war, terrorism, cyber-attacks, civil commotion, fire, flood, earthquake, tornado, tsunami, explosion or storm; pandemic; epidemic and failure of public utilities or common carriers. In such event the Party so failing or delaying shall promptly notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled and shall use commercially reasonable efforts to minimize the duration of any force majeure and resume performance of its obligation as promptly as practicable.  Notwithstanding the foregoing, if such Force Majeure event induced delay or failure of performance continues for a period [***] ([***]) calendar days, after which time the Parties will negotiate in good faith any permanent or transitory modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force majeure and executes such plan within such timeframe.

No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver or subsequent waiver of such condition or term or of another condition or term. No waiver shall be effective unless it has been given in writing and signed by the Party giving such waiver.

13.11.              Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties will negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other

The cytosine and uracil bases are methylated at the 5-position. Each of the 19 internucleoside linkages is a phosphorothioate diester linkage.
